ib_srpt: Remove obsolete parameters and update documentation

Browse Source 
Support for the ib_srpt_target_<n> target port names was removed in 2015.
Update the documentation that still uses this target port name format.
Remove all references to the obsolete ib_srpt kernel module parameters
use_port_guid_in_session_name and use_node_guid_in_target_name. Remove
the references from srpt/README to target port name formats that are no
longer supported.
